The pair dropped the first set but were leading 3–1 in the second when Kato hit a ball to the opposite end of the court and accidentally hit a ball girl in the chest. The ball was not in play then.
The player apologized and was initially given a warning by the referee, but protests by Bouzkova and Sorribes Toromo led to disqualifications for Sutjiadi and Kato, who was in tears as she left the court.
Bouzkova and Sorribes Toromo are thus ready for the quarter-finals, where they will meet the winner of the match between Yifan Xu/Zhaoxuan Yang and Nicole Melichar-Martinez/Ellen Perez.
